Not every manufactured-sand duty needs a VSI. Where the spec allows a cone-cut product — many concrete-sand and road-base markets do — a cone configured for fine crushing delivers the sand at a fraction of the wear cost, because it crushes by compression instead of throwing rock at steel at 70 m/s.
The SK.Y.1200 is that machine: our single-cylinder hydraulic platform in its sand-making configuration. Feed up to 60 mm, discharge set at 8–15 mm, and 40–60 t/h of sub-5 mm product with the balance as usable chips.
Where it fits: smaller sand plants, fine-crushing stages ahead of a washing circuit, and power-limited sites where every installed kilowatt has to earn its tonnage.

Design & working principle
- Compression crushing, not impact — liner wear per tonne is dramatically lower than VSI on abrasive feed; the economics that matter on sand.
- Single hydraulic cylinder — setting adjustment, overload protection and cavity clearing in one system, with fewer seals to fail in tropical service.
- Full product control — the 8–15 mm discharge range sets the sand-to-chip split; tighten it for more sand, open it for more tonnage.
- Same platform as the SK.Y crushers — one spare-parts inventory covers both duties for sites that run SK.Y cones in the main line.
Parameter table
Published as a real HTML table, not a PDF or an image — so it can be read, copied and indexed. Figures are from our own product documentation; the datasheet and GA drawing follow on request.
| Model | Max feed size (mm) | Discharge setting (mm) | Finished <5 mm (t/h) | Main motor (kW) | Weight (t) |
|---|---|---|---|---|---|
| SK.Y.1200 | ≤60 | 8–15 | 40–60 | 250 | 20 |
One model, one duty. For higher sand tonnage, combine this machine in a parallel stage or step up to the SJ.L VSI — send the target tonnage and we will lay out both options with cost per tonne.
Configuration & options
Cavity & liners
Fine-chamber liner set for maximum sand fraction; medium chamber when the chip product also has to sell.
Wet-process interface
Discharge chute arranged for direct feed to a dewatering screen or washing circuit — see Sand Washing & Fines Recovery.
Drive & power
380/415 V 50 Hz standard; 60 Hz to order.
How to choose the right model
- Decide by spec and power, not habit: if your market accepts a cone-cut sand, this machine makes it at lower wear cost than a VSI; if the spec demands cubic particles and a tight fines curve, the SJ.L VSI is the correct tool.
- Size the feed stage to the 60 mm ceiling — a cone stage ahead of it must be set accordingly, which is a plant-design question we answer with the layout.

Common questions
Cone sand maker or VSI — which should I buy?
If your concrete spec accepts cone-cut sand: the cone, for the wear economics. If the spec demands cubical grain shape and controlled fines: the VSI, and no cone will fake it. Send the spec sheet and we will commit to one answer.
